I've been down this path several times and back.
From lowboys to Viper cabs.....1000 in ones to MAME.
I would seriously have a look at GameMasters 'Hankin style' tabletops. They are a nice looking unit or alternatively I would go for a genuine Astro City or Namco Exceelena (not chinese knockoffs).
Depending on what games you want? If its just Galaga + a few others then I would look at a 48 in one, rather than some cheap overseas rubbish motherboard-all-in one...
Or just run MAME yourself. Easy enough to setup, just get the right stuff to begin with ie ArcadeVGA, J-Pac etc..
